Vol.13juni’06Er zijn meerdere goede resultaten beschreven na geslotenrepositie. 6-8 Behoudens milde instabiliteitsklachtenen milde hyperextensie, worden op lange termijnweinig klachten beschreven.Over de niet-reponeerbare knieluxaties zijn weinig resultatengepubliceerd.Bij patiëntje B hadden wij 2 jaar na een open repositiemet een V-Y-plastiek van de quadricepspees een acceptabelresultaat. Langetermijnresultaten blijven tot opheden onbekend. Over de uiteindelijke stabiliteit van dekniegewrichten valt nu nog geen uitspraak te doen.ABSTRACTCongenital dislocation of the knee is very rare. In such cases thetibia is ventrally dislocated relatively to the femur. Congenitaldislocation of the knee can be a part of a syndromal abnormality.As soon as possible treatment by closed reduction with theflexed knee in a plaster should begin. When successful, furtherclosed reduction by progressive flexion and immobilisation ofthe knee can be performed. Usually in such cases the functionalprognosis is favourable.If however, after several weeks the knee dislocation persists, andreduction under general anaesthesia fails, open reduction shouldbe performed. A V-Y plasty of the quadriceps femoris tendon,release of the iliotibial tract and resection of suprapatellarfibrosis usually lead to a good joint reduction.Onze dank gaat uit naar de kinderen en de ouders, <strong>voor</strong> hetverlenen van toestemming <strong>voor</strong> publicatie van de foto’s.LITERATUUR1.
